I asked about that a year ago myself and was told no chance, 
but I think it would be very useful.

I built my own delay box that records the cw if the radio is 
locked out and waits and then sends the stored CW when the 
first radio drops. I still have some bugs to work out but it 
should be workable.

The box I built watches the amplifier relay and PTT lines, 
and the first radio on holds the line. If there is a 
collision the main radio always wins. The thing I missed was 
a cancel send switch in case the held radio needs to cancel 
the memory.
